I haven't yet encountered a situation where the cache was having a problem
and yet was still responding and talking WCCP to the router.

When our Cache Engines have experienced problems, they have removed
themselves from the available pool or stopped responding to WCCP (which,
in turn, caused them to be removed).

In short, I believe there's a very strong mechanism to check all
functions of the cache before saying "hey, I'm okay here".
